Benefits of technology

[0045]According to the present invention, even in the case of performing distortion correction with correction accuracy which is different for each image pick-up mode for photographing a 3D moving image, a 3D still image, or the like, it is possible to obtain a plurality of images which do not have optical axis deviation between images for stereoscopic view after the distortion correction and thus are easy to stereoscopically view.

Problems solved by technology

However, there is individual variability between the two photographing optical systems.
Therefore, when a change in zoom factor together with a lens movement or the like is performed, there arises a problem that the optical axes of the two photographing optical systems deviate in accordance with a zoom position.
In addition, it is extremely difficult to mechanically adjust the optical axes so that the optical axis deviation does not occur over an entire zoom range.

third embodiment

[Third Embodiment of Image Processing Performed at the Time of Continuous Photographing]

[0165]FIG. 14 is a flow chart showing a third embodiment of the image processing performed at the time of the continuous photographing. It should be noted that parts common to those of the first embodiment of the image processing performed at the time of the continuous photographing shown in FIG. 12 are designated by the same step numbers, and detailed description thereof is omitted.

[0166]The third embodiment of the image processing performed at the time of the continuous photographing shown in FIG. 14 is different from the first embodiment in that, from among a plurality of time-series images which are continuously photographed, only an image which is designated by the user to be saved is saved into the memory card 40.

[0167]In FIG. 14, when the switch S2 is turned off (Step S76), the time-series right and left images saved in the RAM 54 are read out and reproduced in photographed order (Step S90...

first embodiment

[First Embodiment of Photographing / Reproduction Process]

[0172]FIG. 15 andFIG. 16 are flow charts showing a first embodiment of a photographing / reproduction process by the stereoscopic image pick-up apparatus 10 according to the present invention.

[0173]In FIG. 15, when the stereoscopic image pick-up apparatus 10 is set to the photographing mode, to thereby start photographing, the image pick-up mode (for example, the 3D moving image photographing mode or the 3D still image photographing mode), the zoom position of the zoom lens, and the optical axis deviation amount at the time of the started photographing are written into a tag of an image file recorded in the memory card 40 (Step S100). It should be noted that the used optical axis deviation amount is read out from the EEPROM 58 or calculated in accordance with the image pick-up mode, the zoom position, and the like.

[0174]In addition, the photographed right and left images with a full angle of view (moving images or still images) a...

second embodiment

[Second Embodiment of Photographing / Reproduction Process]

[0183]FIG. 17 and FIG. 18 are flow charts showing a second embodiment of the photographing / reproduction process by the stereoscopic image pick-up apparatus 10 according to the present invention.

[0184]In FIG. 17, when the stereoscopic image pick-up apparatus 10 is set to the photographing mode, to thereby start photographing, various correction processes are performed on the photographed right and left images with a full angle of view (moving images or still images) (Step S120). The image processing in this case refers to image processing which excludes the image cut-out process for correcting the optical axis deviation of the right and left images and includes white balance correction, gamma correction, shading correction, and distortion correction.

[0185]The right and left images which have been subjected to the image processing are compressed in a predetermined compression format, and then are saved into the memory card 40 (S...

Abstract

Distortion correction with different correction accuracy is performed on images acquired in accordance with an image pick-up mode for a 3D moving image, a 3D still image, and the like, and an image cut-out process corresponding to an optical axis deviation amount of each of right and left photographing optical systems is also performed thereon, whereby optical axis deviation is corrected. In this case, an optical axis deviation amount corresponding to a current image pick-up mode is read out from among optical axis deviation amounts after distortion correction, the optical axis deviation amounts being stored in advance into an EEPROM at the time of adjustment before shipment and corresponding to respective image pick-up modes. Distortion correction corresponding to the current image pick-up mode is performed on right and left images acquired in accordance with the current image pick-up mode. Then, a cut-out process of images for stereoscopic display from the images with a full angle of view after the distortion correction is also performed on the basis of the read-out optical axis deviation amount.

Description

TECHNICAL FIELD[0001]The present invention relates to a stereoscopic image pick-up apparatus, and more particularly, to a stereoscopic image pick-up apparatus which photographs a plurality of images having a parallax therebetween.BACKGROUND ART[0002]In a stereoscopic image pick-up apparatus, with the use of two image pick-up units which are arranged with a parallax to the right and left, the same subject is photographed from right and left points of view, and an image for a left eye and an image for a right eye are acquired, respectively. The right and left images thus acquired are inputted to a three-dimensional (3D) display capable of displaying in a 3D manner, and are displayed so as to be viewable separately by the right and left eyes, whereby the right and left images can be recognized as a stereoscopic image.[0003]Normally, optical systems having the same performance and characteristics are used as photographing optical systems of the two image pick-up units, and the respectiv...
